The RP15-SOF series, are SMD open frame ultraminiature power DC/DC converters in a case half the
size of industry standard 15W converters. The converters use solder ball pins to enable SMD mounting
and can be reflow soldered. Despite their small size, these converters are fully specified devices with
output currents up to 3.5 Amps, no minimum load, 2250VDC isolation and low ripple/noise figures.
The outputs are also fully protected against short circuits, overcurrent and overvoltage. The RP15-SOF
series will find many uses in telecommunications and other demanding applications where cost, board
space or board height is at a premium.

External Output Trimming
Output Voltage Trimming
Single output Powerline converters offer the feature of trimming the output voltage over a certain range around the nominal value by using external
trim resistors. No general equation can be given for calculating the trim resistors, but the following trimtables give typical values for chosing these
trimming resistors. If voltages between the given trim points are required, extrapolate between the two nearest given values to work out the resistor
required or use a variable resistor to set the output voltage. Output can be externally trimmed by using the method shown below.
